' RUBBING-POST.

To all whom t may concern:

Be it known that we, ROBERT F. VRIGHT and 'THOMAS E. VVRIoI-rr, citizens of the Unitedl States, residing at Circleville, in the county of Pickaway and State of Ohio, have invented certain new and useful Improvements in Rubbing-Posts, of which the following is a specification.

The presentl invention relates to an improved .rubbing post adapted especially for antivermin treatment in animal husbandry.

The primary object of the invent-ion is the provision: of anv oiling post against which hogs may rub themselves for antivermin treat-ment, and the construction of existing oiling posts is improved in certain particulars as will be hereinafter pointed out.

In the accompanying drawings we have illustrated one complete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles of the invention.

Figure 1 is a view in elevation of an oiling post involving our invention. Fig. 2 is a vert-ical sectional view of part of Fig. 1.

In the preferred embodimentI of our invention we utilize the post 1 provided with a base 2 through the medium of which the post may be securely anchored against movement due to pushing or rubbing ofthe A reservoir o-r tank 3 1s mounted' animals. above the post in which oil is contained, and the reservoir is equipped with a suitable number of valved nozzles 4, four being indicated in the drawings, although it will of course be und" stood that this number may be varied within limits as described. A top is located on the tank and is secured there on by means of the pin 6 which moves in the bayonet slot 7 indicated in dotted lines.

In the drawings we have illustrated a conventional valved nozzle or nip-ple which is screwed into a perforation at the bottom of the tank. It will be understood that We -may use other suitable forms of nozzles, but however changed the form may be, we 11'1 1 Specicaton of Letters Patent.

rain or snow to the closure of the nozzle end which is normally closed by means of.

a lever l0. Inas uch as each of the levers 10 is similar to tie others, a description of one leve-r will apply to all. The lever 10 is pivoted by rivet 11 in the post, and its upper arm 12 has secured to its inner face a packing disk 13 of leather, rubber, or other suitable material, adapted to close over the open end of the nozzle 4. The nozzle is normally closed' by the lever through the action of the spring 14 which is interposed between the post and the lower arm 15 of the lever.V The inner side of the arm 12 is provided with a. channel formed by the wings or Side flanges 1G, and this channel extends downwardly past the pivot until it merges linto aLl-:orifice or passage 17 through the upper pait of the arm 15. The presence of the passage 17 forms a shoulder or abutment 1S, so that it will readily be seen that when the nozzle 4 is open oil may flow from the tank throughthe nozzle down the channel between the anges 16 and out to the front of the arm 15 through the passage 17,the wall 18 preventing the oil from flowing down the inner surface of the arm 15. The outer surface of the arm 15 is corrugated, as indicated at 19. These corrugations Anotlonly provide a roughened surface against which the hog may rub, but they form ductsy or` canals. for the distribution and retention of the oil as it flows from the nozzle. Because of the presence of the corrugations, the oil is prevented from running off t-he arm asV would be the case with smooth surface, and the oil is also uniformly distributed over th'e face of the arm. The lower end of the arm is projected, ais at 20, from the plane of the arm, by means of which a hog may rub himself-in otherwise inaccessible places.

The operation of the device will be readily understood. The'small or weaker pigs press against the lever where the leverage is greatest, the larger and stronger ones rub where the leverage isless, but the applied power is greater. Pushing in the arm' 15 opens the nozzle 4 so that oil may flow to the outer face of the lower arm 15 as described, and for the purposespccified. The liow of oil from the tank may of course be regulated by the valved nozzles, and the leather pack-l alle 5 We claim as new is An oiling post comprising a tank and a nozzle, a spring pressed lever having an arm to close the nozzle and side flanges forming a :channel which merges into a central dis- 10 tributing orifice through the lever,said lever having a comparatively broad rubbing surface below the orifice, and formed with ay rounded protuberance at its lower end to be engagedy by the underside of an anilnals body.

In testimony whereof we alix our signatures in presence of tWo witneses` ROBERT F wWRIGHT. THOMAS E. lV RIGHT. Witnesses:
